Overview
The Ross 2173B8900 is a solenoid-operated poppet valve designed for precise air and pneumatic control. Built on Ross Controls’ proven poppet valve technology, this model features a 1-3/4 in NPT threaded connection and solenoid actuation for fast, repeatable operation. The valve is ideal for pneumatic manifold systems, industrial automation, and fluid power applications requiring reliable directional or flow control.

Replaces / Drop-In Replacement For
Verify compatibility with your system integrator before ordering. Ross poppet valve designs are generally interchangeable within the same port size and solenoid configuration, but model-specific substitutions require confirmation of pressure ratings, flow paths, and cavity dimensions.
Works With
- AC and DC power supplies (standard industrial voltages)
- Compressed air systems at 15–150 psig working pressure
- Pneumatic control electronics and PLC-based automation
- Manifold cavity blocks and subplate mounting
- Standard pneumatic hoses and NPT-threaded fittings
